NAME

pbmpage - create a one page test pattern for printing

SYNOPSIS

pbmpage [-a4] test_pattern

DESCRIPTION

This program is part of Netpbm(1).
pbmpage generates a one page test pattern to print on a sheet of paper,
for use in calibrating a printer. The test pattern in is PBM format.
pbmpage produces an image intended for 600 dots per inch printer reso-
lution.
If you are printing on an HP PPA printer, you can convert the output of
this program to a stream that you can feed to the printer with pbm-toppa.
Bear in mind that when you print the test pattern, you are testing not
only the printer, but any converter or driver software along the print-
ing path. Any one of these components may adjust margins, crop the
image, erase edges, and such.
If, due to addition of margins, the printer refuses to print the image
because it is too big, use pamcut to cut the right and bottom edges off
the test pattern until it is small enough to print.
test_pattern is the number of the test pattern to generate, as fol-
lows. The default is 1.
1 A black on white grid ruled in numbers of pixels. A black one
pixel box is at the very edges of the paper.
Before Netpbm 10.18 (August 2003), the perimeter box was not
there.
2 A vertical line segment, one pixel wide, extending 1/2’ up from
the exact center of the page.
3 Two diagonal line segments, one starting at the upper left cor-
ner of the page, the other starting from the lower left corner
of the page. Both extend 1/2’ toward the center of the page at
45 degrees.
